Abstract: A landing gear (10) for semitrailers includes a two speed double reduction gear assembly (34, 40) having fewer, smaller, and simpler parts, resulting in a compact double reduction gear assembly housed in a relatively small gear box (55) or entirely within one of the landing gear legs, which is a cost efficient landing gear unit with a unique clutch-shifting mechanism (85, 86) to provide for shifting from one ratio to another. The double reduction gear assembly is disposed on and about in-line input and output shafts (75, 42) further resulting in an easy to crank and shift landing gear unit capable of achieving standard crank handle turn to vertical leg travel distance ratios. The low gear or low speed ratio of the landing gear unit can be varied within a broad range during manufacture, if desired, generally without increasing the overall size or complexity of the two speed double reduction gear assembly. The landing gear can further include a universal mounting feature (16) and is durable and simple to use.

Abstract: The invention relates to a hardware electronic ASIC prototyper which enables integrated circuits or ASICs to be emulated so that it is possible to test the chip to be created in the later hardware environment. Emulation systems are known which consist of a matrix of configurable logic blocks, configurable I/O cells and a configurable wiring. These systems only emulate the functional behaviour of the desired circuit.   According to the invention, adding programmable delay units into the logic cells and using programmable switching networks with delay units for interconnecting the logic modules formed from a plurality of logic cells has the result that the time characteristic of an ASIC is taken into consideration in the emulation so that complete emulation is achieved. By deliberately setting all inputs to a defined logic state, an error emulation can be achieved. The detection of "race" problems is possible by means of the programmable delay units. <IMAGE>

Abstract: Object of the Invention 
     To enable the measurement of the absolute voltage of the wiring under test with no cross-talk and without depending on the gap interval between the probe tip and the wiring under test. 
     Construction of the Invention 
     The voltage of the conductive films 22 to 24 are controlled by the feedback circuit 55 so that the output of the differential amplifier 52 is equal to zero, for example. No external electric field is applied to the pinhole h, and the voltages of the conductive film and the wiring under test 12 are equal to each other. 
     The variation in polarization of the measuring light in the electrooptic material 21 is detected as a difference in potential occurring in the electrooptic material 21, and the voltage of the wiring under test 12 is measured on the basis of the difference in potential. Since the voltage of the conductive film is compared with the voltage of the wiring under test, even when an error occurs in distance between the non-contact type probe 20C and the circuit under test 10, this error does not appear as an error for the voltage measurement, and thus the voltage of the wiring under test 12 can be measured with high precision.

Abstract: Computers are linked together to form a network. Messages are sent over the links between the computers in compressed, segmented form, the size of the segments being appropriate to the transmission characteristics of the link. A message previously received or transmitted by a computer is stored in compressed and segmented form. If it is desired to forward or retransmit this message, the segment size of the stored form is compared against the optimum segment size for the link over which the message is to be sent. If there is a close match, then the stored segmented, compressed message is retrieved for direct transmittal, without having to resegment or recompress the message.

Abstract: The invention relates to a radiant heater for glass-ceramic cooking surfaces, in which electrical heating resistors, constructed as heating filaments, are fastened together with strip-shaped holding elements on the lower part of the insulating body. It is the object of the invention to propose designs of the strip-shaped holding elements which result in an additional positive fastening of the holding elements in the lower part of the insulating body. According to the invention, this is achieved in that the strip-shaped holding elements (4) are provided with perforations (9) in that area which is to be incorporated in the lower part (2) of the insulating body, through which perforations the insulating material can penetrate during pressing during the manufacture of the lower part (2) of the insulating body. After the lower part (2) of the insulating body has cured, this results in a permanent positive connection between the holding element (4) and lower part (2) of the insulating body. <IMAGE>

Abstract: A magneto-optical recording and reproducing device is provided with a magneto-optical disk (201) for reproducing recorded information using light, a semiconductor laser (101), an objective lens (105) for converging a light beam emitted from the semiconductor laser onto the magneto-optical disk and a light interrupting member (120) for interrupting a portion of a light beam before it is incident on the objective lens. The magneto-optical disk is composed of a readout layer which is predominant in in-plane magnetization, and in which a transition occurs to be predominant in perpendicular magnetization as temperature thereof is raised and a recording layer for recording thereon information using a perpendicular magnetization. In this arrangement, since the light interrupting member is provided, a light spot can be made smaller, thereby improving a recording density. Moreover, even when temperature of the readout layer is raised due to a side lobe generated by the light interrupting member, in-plane magnetization is maintained in the readout layer. Thus, interference by unwanted reproducing signals due to the side lobe can be prevented, thereby improving a reproducing signal quality.

Abstract: A multiple-orifice phase-change ink-jet print head (28, 44) is heated by a composite laminate heater (29, 58) having multiple heating zones (31A-31K, Z1-Z28) spanning the X- and Y-directions of the print head. The print head has multiple rows of ink-jet orifices (34, 46) spread across its face in the Y-direction with the ink in each orifice in each row requiring substantially the same temperature to ensure a uniform jetting velocity from every orifice. In one embodiment, the print head is in fluid communication with a thermally massive multicolor ink reservoir (52) that conducts heat through a region of contact (92) with the print head. A rotating drum (32), spaced across a gap (90) from the print head, draws air through the gap thereby cooling the print head differentially in the Y-direction. Radiation and convection are further thermal transfer mechanisms that contribute to a nonuniform temperature throughout the print heads. The heating zones of the print head heaters compensate for the various thermal transfer mechanisms to cause a uniform temperature throughout the print heads. A temperature controller (16) requires only a single temperature sensor (18, 104) to regulate print head temperature.
